Benefits of technology

This patent relates to a method and apparatus for treating emphysema by using mechanical compression to reduce the volume of diseased tissue. This compression helps to restore some of the elasticity of the tissue and allows airways to remain open. This procedure is minimally invasive and safer than surgery. The patent describes an anchoring system that can be adjusted to decrease the distance between anchors, which can be done by shortening the tether between them or reducing the amount of tether. This reduces the likelihood of inflammation or other complications. The remaining portion of the lung functions while the volume of the affected area is reduced.

Problems solved by technology

Twisting or spooling of the tether and thereby managing any and all excess tether length that may result from the tensioning and foreshortening of the tether on implementing a lung volume reduction reduces the likelihood of the anchoring system causing an inflammatory response within the lung.

Embodiment Construction

[0090]The disclosure describes methods, devices, and systems for reducing the volume of a lung.

[0091]FIGS. 1A-1C and 2 illustrate an exemplary embodiment of a lung volume reduction apparatus. The embodiment in FIGS. 1A-1C and 2 is an example of a device for reducing the volume of a lung that includes a distal anchor, a proximal anchor, and a tether extending between the distal and proximal anchors, the device configured so that the distance between the anchors measured along the tether can be increased or decreased and maintained after release of a delivery device. Apparatuses and devices configured and / or adapted to reduce the volume of a lung may also be referred to herein as “treatment devices.” The apparatus shown in FIGS. 1A-1C includes three components. The first component is an airway anchor (1001) as shown in FIG. 1A. An “airway anchor” may also be referred to herein as an “airway anchoring device” or other derivative. The airway anchor is designed to be collapsed into a sma...

Abstract

Methods of treating COPD, including bronchoscopically positioning a lung anchor in lung tissue, positioning an outer implant member in pleural space proximate the lung anchor, and coupling the lung anchor to the outer implant member and thereby compressing lung tissue.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to the following U.S. Provisional Applications, each of which is incorporated by reference herein in its entirety: Application No. 62 / 371,171, filed Aug. 4, 2016; Application No. 62 / 376,874, filed Aug. 18, 2016; and Application No. 62 / 384,189, filed Sep. 6, 2016.INCORPORATION BY REFERENCE[0002]All publications and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.BACKGROUND[0003]Lung volume reduction (LVR) is an important procedure in the treatment of emphysema or chronic bronchitis, a form of Chronic Obstructive Pulmonary Disease (COPD). COPD is the third leading cause of death in the United States. Emphysema is a type of COPD involving damage to the air sacs (alveoli) in the lungs. As it worsens, emphysema turns the a...
